1070 aluminum PS CTP plate

Mar. 06, 2025

At present, aluminum substrate still occupies a dominant position among PS CTP board substrates. 1070 aluminum alloy PS CTP plate is a high-quality printing plate. The width range of PS/CTP plate base is generally 400-1600mm, and the conventional thickness is 0.10- 0.50mm.

1070 aluminum PS (Presensitized) CTP (Computer-to-Plate) plate is a high-quality printing plate widely used in the printing industry. Made from 1070 aluminum alloy, this plate is known for its excellent offset properties, durability and high performance in a variety of printing applications.

The traditional hot-rolled 1050 industrial pure aluminum PS CTP board base has impurity band defects. The internal cause is the high content of Fe, Ti and other impurities in the chemical composition of the aluminum plate matrix, and the external cause is impurity pressure and scratches. Use 1070 with higher aluminum purity to replace 1050 alloy, and appropriately adjust the process to achieve mass production of high-quality, efficient, and energy-saving PS CTP board bases.

1070 aluminum PS CTP plate specifications

PS CTP aluminum plates are usually made of h18 alloy, and 1070 is also widely used in PS plates, thermal CTP plates, photosensitive CTP plates, UV-CTP plates and other offset printing plates.

1070 aluminum alloy is a pure aluminum alloy, also known as "industrial pure aluminum". Its aluminum content exceeds 99.7% and has the characteristics of high density, high strength, moderate wear resistance, easy forming and high stability.

1070 aluminum PS CTP plate features

• It has the characteristics of high resolution, high dot reproducibility, high printing durability and good printability.
• It uses a special photosensitive coating to make the plate making process easier and faster, while improving the quality and stability of printed matter.

Advantages of 1070 aluminum alloy PS CTP plate

• 1. High-quality printing effect: The high purity and stability of 1070 aluminum alloy provide an excellent printing foundation for the PS CTP plate, allowing the printed matter to have higher resolution and dot reproducibility.
• 2. Good processing performance: 1070 aluminum alloy is easy to process into various shapes and sizes, and can meet different printing needs. At the same time, its good electrical conductivity also contributes to charge distribution and transfer during the plate making process.
• 3. Environmental protection: Aluminum alloy materials are recyclable and meet environmental protection requirements. At the same time, PS CTP plates also reduce the generation of waste liquid and waste materials during use, reducing the impact on the environment.

1070 aluminum CTP PS plate manufacturing process

1. Rolling: Aluminum ingots are hot rolled to achieve the required thickness, and then cold rolled to improve surface finish and mechanical properties.

2. Surface treatment: The rolled aluminum plate undergoes surface treatment to improve its lithographic quality. This usually includes:

• Granulation: A mechanical or electrochemical process that roughens the surface and improves ink adhesion.
• Anodizing: An electrochemical process that creates a layer of aluminum oxide that increases surface hardness and wear resistance.
• Coating: Apply a photosensitive coating. This layer is critical to CTP technology because it reacts to exposure during imaging.

1070 aluminum PS CTP plate is a key component of modern printing technology. It combines high-purity aluminum, superior mechanical properties and advanced surface treatments to ensure top performance in demanding printing environments. This makes it an indispensable choice for industries that require high-resolution, durable and reliable printing solutions.
